Over-exertion in lifting objects
IE and another EE were moving a 125 lb grease container. EE got busy and IE decided to move the container on IE's own. IE lifted up the container and tried to put force on IE's arm to keep the barrel from falling and felt a stretch on IE's left bicep and shoulder. On 5/01/19 IE informed us that IE had a torn rotator cuff and will be needing surgery.
